Help Manually Setting Bed Plane
I have a #Printrbot
Metal Simple with the Z-probe. At the start of a print, I run a G29 command to probe the bed level and determine the bed plane. This reports values in the form.
< 11:34:56 AM: Bed x: 10 y: 142.40 z: 0.42
< 11:35:04 AM: Bed x: 10 y: 10 z: 1.63
< 11:35:12 AM: Bed x: 142.40 y: 10 z: 1.72
These values will vary +/- 0.05 mm between calibration runs.
This works well enough for most prints but are not quite repeatable enough for print in place designs with very tight tolerances or low layer height prints where a 0.1mm height difference between corners may cause the print to fail.
I would like to manually set the z plane by setting the bed plane in Gcode at the start of the print. ie. Manually set the z value for 3 points as above. Any hints on what gcode to use to do this?
Is it possible to have the bed probed at more points? I noticed that the Afinia leveling scripts tests 9 points. Code suggestions?
